(A) No person shall discharge or cause to be discharged any storm water, surface water, ground water, roof runoff, sub-surface drainage, cooling water, or unpolluted industrial process waters to any sanitary sewer.
(B) No person shall discharge or cause to be discharged to any public sewer, any harmful waters or wastes, whether liquid, solid, or gas capable of causing obstruction to the flow in sewers, damage, or hazard to structures, equipment, and personnel of the sewage works, or other interference with the proper operation of the sewage works.
(C) The admission into the public sewers of any waters or wastes having harmful or objectionable characteristics shall be subject to the review and approval of the Superintendent, who may prescribe limits on the strength and character of these waters and wastes. Where necessary, in the opinion of the Superintendent, the owner shall provide, at his or her expense, such preliminary treatment as may be necessary to treat these wastes prior to discharge to the public sewer. Plans, specifications, and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the said Superintendent and of the state’s Board of Health, and no construction of such facilities shall be commenced until said approval is obtained in writing. Where preliminary treatment facilities are provided for any water or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his or her expense.
(D) When required by the Superintendent, the owner of any property served by a building sewer carrying industrial wastes shall install and maintain, at his or her expense, a suitable control manhole in the building sewer to facilitate observation sampling and measurement of the wastes. All measurements, tests, and analyses of the characteristics of waters and wastes shall be determined in accordance with Standard Methods for the Examination of Water and Sewage, and shall be determined at the control manhole or upon suitable samples taken at said control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected.
(E) Grease, oil, and sand interceptors shall be provided when, in the opinion of the said Inspector, they are necessary for the proper handling of liquid wastes containing grease in excessive amount, or any flammable wastes, sand, and other harmful ingredients except that such interceptors shall not be required for private living quarters or dwelling units. Where installed, they shall be maintained by the owner, at his or her expense, in continuously efficient operation at all times.
